Fungi

How does the proportion of mutualist fungi relate to indicators of plant health?

In the following figure, the X-axis represents the proportion of fungi that could be identified to a mutualistic guild; the Y-axis represents the value of the various measures of plant success (facets). Y-axis scales vary between facets.

Figure 15

We see an opposite pattern when looking at the proportions of putatively pathogenic fungi

Important Taxa

These taxa were identified by both Random Forest models and corncob as being important predictors of the various experimental conditions & had significant differential abundance between levels of those variables

Phylogenetic properties

Bacteria

  • Still kind of messy
  • What specific questions do we need to address with this?

Fungi

  • Phylogenetic dispersion is tricky with ITS markers :(
  • Could try GhostTree for fungi of interest that come up as ‘unknown’

Soil chemistry

Overview of soil properties for each inoculum source:

Testing for significant differences between the samples…

Here are the soil properties that differ significantly between inoculum sources. Sterile inoculum soils are set as the intercept. The stats below pretty nicely reflect the obvious patterns in the overall figure.
